IMPROVEMENT lN SUPPLY AND'WAST'E-COCKS.

Specification forming part of Letters Patent No. 117,606, dated August1, 1871.

To all whom it may concern:

Be it known that I, WILLIAM SAMUEL COOPER, of Philadelphia, county ofPhiladelphia, State of Pennsylvania, have invented an Improved Supplyand VasteCock or Faucet, of which the following is a specication:

My invention consists of a supply-cock or faucet, con structed in themanner too fully described hereafter to need preliminary explanation,with the view of ei'i'ectually disposing of the waste water after thevalve of the cock is closed, and with the further object of preventingleakage.

Figure l is a longitudinal section of my improved supply and waste-cockor faucet, showing the valve depressed; Fig. 2, the same with its valveelevated; Fig. 3, a sectional plan on the line l 2, Fig. l; Fig. 4, asectional plan on the line 3 4, Fig. l 5 and Fig. 5, a sectional plan onthe line 5 6.

The body of the faucet consists of an inletbranch, A, and outlet-branchA, and the branch B for the reception of the valve. The inlet andoutlet-branches are separated from each other by a partition, a, inwhich is an opening, b, closed by a valve, d, when the latter isdepressed, as shown in Fig. l. This valve is attached to or form s partof the valve-stem D, the upper threaded portion j' of which is adaptedto a nut, E, passing through the screw-cover F of the branch B andterminating above the same in a suitable handle, h, and below in aflange which fits snugly, but so as to turn freely, in the interior ofthe branch B, this flange having an4 annular groove, i, whichcommunicates with the interior of a small wastebranch, m, Fig. 4, thegroove being always in communication, through the openings p, with therecess n in the bottom of the nut. The plain portion of the stem Dimmediately above the valve is square, and passes through a Square holein a disk, a', which rests on a ledgeviu the branch B, the disk beingprevented from turning by its projection q fitting into a verticalgroove in the said branch and the square hole in the disk, beingSomewhat larger than the square portion of the stem which passesthrough. it. The nut E is held in place by the screw-cover F into aninternal recess, in which is forced a packing, t, for embracing the nut,as shown in Figs. 1, 2, and 3.

When the valve is raised, as seen in Fig. 2,

there is a free passage for the iiuid through the branch A, hole b inthe partition a., and branch A', and the valve, bearing on theintermediate loose ring n, has compressed the loose annular packingagainst the lower end of the nut, (see Fig. 2,) thereby effectuallypreventing the fluid from rising in the branch B above the said packingand escaping through the waste-branclfm. On depressing the valve,however, the waste water in the branch A' and the pipe connected to thesame will pass between the ring or disk n and the valve-stem, thenceinto the groove of the flange at the lower end of the nut, and thencethrough the waste-branch m. The tendency of the Waste water to passupward between the cylindrical nut and the cap is effectually preventedby the annular packing t, which is forced into the annular recess of thescrew-cap before the nut is passed through the latter.

It Should be understood that supply-cocks of this class are rarelyarranged in the position Shown in Fig. l, the usual position beingvertical, with the branch A uppermost; or, if the cock is arrangedhorizontally, the wastebranch ou should project downward, as shown inFig. 4.

In either case the waste water, on closing the valve, is effectuallydrained from the branch A and from the pipe communicating therewith.

I claim- 1. The combination, in a supply and wastecock, of a rotatingnut, E, having at the lower end an annular recess, u, and open rings ii, the waste-pipe m arranged aS described, and a vertically-movingvalve, d, between the stein of which and the casing is an annularpassage through which, when the valve is closed, the water can ilowdirectly from and through the Acasing around and above the valve, asspecified.

2. The combination of the above and the loose ring or disk n and thepacking arranged between the same and the nut.

In testimony whereof I have signed my naine to this specication in thepresence of two subscribing witnesses.

WM. S. COOPER.
